As a general statement the traditional pigments granulate, e.g. earths, ultramarine. The modern organic pigments do not, e.g. Cotman hue colours. If you wish to avoid granulation in your painting, the use of distilled water can reduce it, particularly in very hard water areas. Staining Cotman's architectural etchings have long been considered as a valuable record for historians. [24] Reputation and legacy [ edit ] House in the Place de la Pucelle, at Rouen, etching, Architectural Antiquities of Normandy (Vol. II), Pl. 64, 1821 You can always buy the watercolour in tubes to refill your used pans. Watercolour tubes are cheaper. A 5ml tube cost as much as a half pan but can probably refill it about 2-3 times. Comparatively cheaper!

The distillation of petroleum yields an ever widening range of organic pigments which are often termed as 'modern'. Many of the pigments used in Cotman are organic. Colour Range As a general statement the traditional pigments granulate, e.g. earths, ultramarine. The modern organic pigments do not, e.g. Cotman hue colours.

A comprehensive catalogue by Emeritus Professor David Hill of The University of Leeds, covering the entire Leeds collection of Cotman sketches and watercolours, together with one oil painting. A smaller box is more portable. And 12 colours is a lot for starters. Too much colours can get confusing.Winsor & Newton Cotman Water Colours are a range of water colours that are made to our normal high quality standards but costs are kept to an economical level by replacing some of the more costly pigments with less expensive alternatives. The modern organic pigments, e.g. Cotman hue colours, are made of very fine particles which cause them to stain the paper. The traditional colours e.g. earths, tend to lift from the paper more easily. Although Cotman drew a lot of attention with cotton watercolor paper, I didn’t think these characteristics could be duplicated on standard paper–even if the papers were of high quality. Cotman, on the other hand, is student grade watercolors that I tested a couple of years ago, and my impressions are still excellent. Choosing Between Pans And Tubes Of Paint The Chinese White included isn't quite useful here. Chinese White when mixed is used to tint brighter colours, basically make a lighter version of the colour. Remember than the Cotman colours aren't as intense so Chinese White is not going to be as useful. However, it's opaque so you can use it in concentrated form to cover up mistakes or for special uses such as dotting the eyes. Cotman is the range of student grade watercolours from Winsor & Newton. The professional grade is called the Artists' Watercolour or the Professional Artists' Watercolour.

There are two grades of paint. The artist grade is more expensive than the student grade. Just go for the artist grade straightaway because they are going to last quite long, even if they are only half pan. Cotman watercolors are a high-quality, affordable option for artists of all levels. They offer excellent lightfastness and vibrancy, and their wide range of colors allows for endless creative possibilities. Whether you’re just starting out or are a seasoned professional, Cotman watercolors are a great choice for your next project. Are Cotman Watercolors Good?In 1800, Cotman exhibited at the Royal Academy for the first time. [3] He exhibited other Welsh scenes at the Royal Academy in 1801 and 1802. [10] In 1800, he was awarded an honorary palette by the Society of Arts. [3] He continued to exhibit at the Academy until 1806. [11] He was based during the early 1800s in London, but is known to have advertised in Norwich—in September 1802 he advertised his services as a drawing teacher in the Norwich Mercury. [12] Yorkshire visits (1803–1805) [ edit ] Winsor & Newton probably has more box sets than other manufacturers. The box can be made of metal or plastic. There are palette boxes that hold up to 48 colours (not recommended unless you're a professional but if you're a professional you'll probably know you won't need so many colours). Cotman Water Colours are a range of water colours that are made to Winsor &Newtons normal high quality standards but costs are kept to an economical level by replacing some of the more costly pigments with less expensive alternatives. The range consists of 40 colours in tubes and panswhich possess good transparency, excellent tinting strength and good working properties. There are also a number of excellent water colour sets available in the Cotman range. Sizes Available

(Subscription or UK public library membership required.) Born in Norwich, the son of a silk merchant and lace dealer, Cotman was educated at the Norwich Grammar School. He showed an early talent for art. It was intended that he followed his father into the family business but, intent on a career in art, he moved to London in 1798, where he met artists such as J. M. W. Turner, Peter de Wint and Thomas Girtin, whose sketching club he joined, and whom he travelled with to Wales and Surrey. By 1800 he was exhibiting at the Royal Academy, showing scenes of the Welsh countryside there in 1801 and 1802. His drawing expeditions took him throughout southern Britain, and to Yorkshire, where he stayed with the Cholmeley family during the three summers of 1803–1805. Lyles, Anne; Hamlyn, Robin (1997).

Then there are 5 convenient mixtures of two greens and three earth colours. It's quite a complete set in terms of colour selection. In 1834, Miles Edmund remained in Norwich to work as an art teacher, when the rest of the Cotman family moved to London upon Cotman's appointment at King's College. A year after his move to London, Mile Edmund moved to London to be his father's assistant, after his brother John Joseph returned to Norwich. [23] Miles Edmund succeeded his father as drawing master at King's College in 1843.

I like this box set because it's larger but I hate that the pans are not totally secure in their housing. Winsor & Newton Metal Sketchers' Box In late 1806, Cotman returned to live in Norwich. He joined the recently-formed Norwich Society of Artists, exhibiting 149 works with the society between 1807 and 1810. [13] He became President of the Society in 1811. In the three summers of 1803–1805, Cotman stayed with the Cholmeley family at Brandsby Hall in Yorkshire. [1] On the last of these three visits from London, [note 1] he made a series of watercolours of the River Greta, [11] after he was invited to visit Rokeby Park, the home of the English traveller John Morritt. Cotman's delicate paintings from these visits are among the finest produced by a European watercolourist.

For example, 'Cadmium Red Pale Hue' in Cotman Water Colour is a 'colour of cadmium red pale'. A hue colour is not necessarily inferior. Mixing Colours As part of his teaching, Cotman operated his own version of a watercolour subscription library, so that his pupils could take home his drawings to copy. [13] In 1810, Cotman began to etch, and the following year his first set of etchings ( Miscellaneous Etchings) was published, strongly influenced by the work of the Italian artist Piranesi. [13] All but one of the subjects were architectural, and were mostly of Yorkshire buildings. [18] He later published a set of etchings of the ancient buildings of Norfolk ( Architectural Antiquities of Norfolk (1818). [13]Winsor & Newton is one of the leading brands of professional watercolor paints.

The paints are known for their rich pigmentation, excellent colorfastness, and smooth flow. Winsor & Newton offers a wide range of colors, and their paints can be used for a variety of techniques, from traditional washes to more experimental approaches.
